Application filed May 27, 1903, Serial lie. 153,963.

To all whom it may concern:

Be it known that I, GEORGE W, 1302mm c, a, citizen of the United States,residing at East Orange, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in ElectricalType-Writer Selecting and O crating Means; and I do hereby declare theshowing to he a full, clear, and exact description of the inven tion,such as will enable others skilled in the art to which it appertains tomake and use the same.

,The object of this invention is to provide an-irnproved means foroperating rind control g the writing mechanism for electrically-operatedtype-writing machines, and is to be distinguishedfrom my copendingaplication, filed of even date herewith, Serial 0. 158,962, therein theobject is to provide a key mechenism that when depressed will firstcomplete a circuit including a selectingmagnet and position a type-barmember and upon further depression was break said circult andsimuitsneously close a circuit in cluding a universal power-bar, therebycausing a t p'e-bsr corresponding to the key do presse to be operatedand print a character 77 In the present invention the object is toprovide a key mechanism that will first complete a circuit including. aseiecting-msgnet andposition a t is-bar member and upon furtherdepression will break the circuit.

en upon still further depression it will make a circuit including amagnet that will operate a type-bar which has boon positioned and causeit to printits character. lVhen member connected with thstype-bsr hasbeen positioned, a suitable latch 18 caused to engage the. mcmlu-rconnected with tho typo hm and retain it in position until engaged bythe atusting-har.

Another object is to provide an improvcd form of kcy or switch forcontrolling and opcrating such electricallyand operating mechanism. V r

A further object is to provide a krymocls anism which will effects cycleof movement of operative parts as follows: first, electrical connection.with n selecting-magnet to attract.an-arrnsture-oarrying pawl or leverthat is suitably fills-ruined and which is thrrebv positioned forfurl-her operation; second, switching of the current from the saidmagnnisrmsnct e'r to shift the another to shift the ribbon pcratodsolcctingi net to a second niagnet to effect electrical connection witha magnet to attract the armaturc of an actuating power device, duringwhich latter movement the pawl or lever is engaged hy th'e power device,and tho operative parts (that head, a shifting actuator, or other 0crating part of a type-writer) are operated or a desired purpose, and,third, to break the circuit in order to cause return of the said partsto normal positiom'ail upon the down movement of thckey.

A further object is to provide novel constructions sngi arrangements foreffecting the-so operiitions.

A further object is to provide a key constructiofirrliich will whencooperating with an outside soiirce of power andwhen op stated performsefeiiil notions-namely, select. operate, permit return of the operatedparts ini'lejiendcntly of the release of the key. The same msy be emloyed to o crate thc typingsnd sscing anlih'ibbon-fcc ing mechtypo-hcsd,and and other fn'g' any desired Inechnnisnion the i i 'riot herohj ectis to provide a form of kev that will firsifenergize one-of a set ofselect iugmiagnstsythen upon a further movement ,vrili' cut out the'saidmagnet, and upon astill inrth'cr advance will energize a power-mag-;not, and upon a still further advance will cut out'thcpower-magnet, andupon release of tho key it will return to its normal posi Lion withoutenergizing of the magnets.

Vfith thcsc'obficts in view and others my invention comprohcnds theconstruction, as

mngomont, sud comhinstiol'l -of parts,

hereinafter described and claimed. 7 V

'ii'cferriug to the drawings reprcsesing nn apparatus elnbodying myinvention, Figure '1 is a front porspelct V View, certain parts beingomitted; Fi Q. 2 is s vertical section through thc midis oi'tlicmachine. Fig. 3 is a sin'iiii 7 f a modification. r

In tiii sovornl vicws the characters of roicrencoiiidiciitc the somepart.

In it fro-ms A n're secured fulcrum-rods a a, that. carry Isss'm a,respectivcl which lattor support bent lovers 0 a, one of the bent leverslining snpportcd by a link a and a; 1 1k a, preferably arranged inparallelism. When may he a typo-bar or a t c- ,7

psrts one of the bent levers a is depressed, it will rock a type-bar ofthrough the medium of a lever 01 and connecting-links a" a i A universalpower-bar B extends between the links a and a and is supported at eachend by an arm I), pivoted to the side late of the machine. On each sideof the 'nks a is pivoted an armature-lever c, carr ing an armature 0arranged to be attracts by one of a series of elcctromagnets 0 carriedon a bar c, of fiber or other suitable non-magnetic material. Aretractile spring 0 serves normally to retain the armature-lever c inthe position shown and awe from its operatingmagnet. The lower an ofeach of these armature-levers c has a hook-shaped foot or offset 0, thatwhen the armature-lever is rocked through the influence of itscontrolling-magnet will be moved under the universal power-bar B; butwhen the magnet is again de'e'nergized the retractile spring will movethe foot away from its position of engagement with the power-bar.

On the base-plate is mounted an electromagnet D,having, preferably, twocoils cl (1 An armature (1* is suspended within range of the influenceof the magnet D, bein pivoted on a bar (i that is carried b two levers dd", the latter being pivoted at 7 to the side of the machine. The leversd (1 each have an arm (1, that is pivoted to one of the arms I). Aretractile spring d serves normally to retain the armature, theuniversal power-bar, and their connected parts in the position shown inthe drawings and away from the electromagnet Consequently when theelectromagnet D is energized the armature will be attracted and rock thelevers d", the arms (I thereon, and then the pivoted arm 11 downward andalso the universal power-bar B. New should any of the selecting-mag netsbe energized, and thereby brin one of the feet 0 under the universalpowerar, and thereupon the electromagnet Dis energized, the power-barwill engage the hook c in its downward movement, and thereby o erate thecorresponding type bar throug the aforesaid connecting members.

In my said application filed of even date herewith the armature-lever isretained in position by the selecting-magnet until the operating-1nagnetmoves the power-bar to engage the hook on the lever by reason of theform of switch there employed. In the present invention I provide alatch E, pivoted on ear-h of the links a? a and resting upon thearmature. When any of the armatures is attracted by its magnet, thelatch will fall and bring its notched part (2 back of the ar mature, andthereby retain the armaturelevcr with its foot underneath the powerbar;but when the link a and comics-ted parts are carried down by thepower-bar a stationary rod 6 will strike the latch and arrest itsmovement, while the armature continuing to descend will cause the latterfo be discharged from the notched part of the atch.

For each of the selecting-magnets 0 there is a three-terminal switch,preferably such as shown. In an. insulatin -block F is a metal bushingf, in which sides a stem f having a key f A plate f carries the block Fand also an insulating-block f that guides the end of the stem f, whichlatter has a coilspringf, that returns it when depressed. Aspring-terminal f is secured to the block F and is connected by suitableconductor with one terminal of a power-bar-o crating magnet. Anotherspring-termina 8 is secured to the insulatin -block f and is connectedby suitable con uctor with one pole of the selecting-magnet. The otherpole of the selecting-magnet and also the other pole of the ower-ma netare connected by suitable con uctor wit one terminal of a source ofelectric current, such as a battery G. The other terminal of the batteryis connected with the bushings f of all the keys.

When the key-stem is depressed a short distance, a cross-bar f a on thestem strikes a projection f on the terminal blade f there y completingthe circuit including the battery and the selecting-magnet. This willcause the armature of the selecting-ma net to be rocked and bring thehook-shaped not of its lever under the ower-bar B. .At the same time thlatch will under its own weight have fallen so as to cause its notchedend e back of the armature, and thus hold the armature-lever with itsfoot under the powerbar. A further movement of t ke '-stem will positionthe cross-bar f 9 beyond t e pro jection of the terminal blade f thuscutting out the selecting-magnet and breaking the current; but the latchwill not have become disenga ed from the armature which it is then hedihg, but will tend to retain the armature-lever with its hook under thepower bar until disengaged therefrom in the manner already abovedescribed. Thereupon a further advancement of the key-stem will causethe bar f to strike a projection f on the terminal thus completing thecircuit a second time, including the battery a second time and thepower-bar magnet once or for first time,

which will cause the powersbar to operate the type-bar, as hereinbeforeset forth. A further depression of the key-stem will cause a pin f onthe key-stem'to move an insulating-leverf down and strike the bent end fof the terminal blade f and move this blade so that its projection fwill be out of range of e gagement with tl e crossbar f breaking thecircuit through. said terminal blade f and permitting ret.um'.t0 normalposition of the operating partsindependcnt of return of key. At the"same time a pin f on the keyste m will .cause an insulatinglever f movethe terminal blade f so barf impinges against the offset or petite:

the cross-bar shall have passed the projections, A Thereupon in thecontinuation of the upward movement of the key-stem the pins f" and fwill strike the levers and raise them to their former. positions and atthe same time release the terminal blades.

In Fig, 3 I have shown another form of de vice for effecting theretainin of the selectlug-pawl durin any possible interval in the actionof switc ing from one circuit to the,

'ftien is different from that eonstitutin subject-matter of myaforementione other. In this construction the latehesfE and bar a areomitted and a permanentlymagnetized armature c is emplo ed and which isconstructed ofa metal or al 0y, such as Russia iron, that will retainthe magnet isrn induced in it by the engaging GlQCtIOIQEt net for ashort period of time, suilicient for retaining it in proximit to the menot with its lever-foot underneat the powerar until the latter shall beactuated by its magnet and enga e this foot and draw the lever downwarand thus remove the face of the armature from the field of attraction,as by drawin it down beond the face of the magnet, wl ich may, idesirable, be provided with a roiecting face of suitable dimensions. Uon tlle release of the power-bar the retracti e s ring will withdrew thearmature from the e ectromagnet'.

The depression by the operator of the means (colnprisin the key-stem fto select a articular type or and for creating a pin 'ra ity of electriccircuits actuates or -projects it and its adjunotive parts to one of apluralitv of operating or circuit-creating positions.

e first circuit is established when the crosstionf, arranged onthe'terininalj", and the o eration of this circuit positions the latchso t at it can be operated. by the powcr bar when actuated. Theadditional continued projection of said key-sfern f" positions the thusreek the circuit, as the latch has there- .by been properly positioned.-lhc further" depression or pro ection of the key-stein actuates thepower-bar to Opiaratotlie latch and'the type-bar. A further projectionof said key-stern positions the levorj against that terinii'lalandbreaks the circuit tlltt(&--

through.

ation directed as a different an ever to force the terminal outward,and" My invention is to be distinguished from other devices in the artin that in operation the parts are'operated by a single circuit derivedfrom a single source, which circuit is created three b one terminalfirst to effeet one operation, then interrupted through thateircuit andsimultaneously. transmitted through a rliflerent terminal to effect adiflerent operation, and so on, which circuit through the medium of myinvention is under positive control, first directed as adistinct circuitto a selecting-magnet to position 'a movable part. for actuation andthen and in i succession and as a distinct and gositire open distinctcircult to a power-bar operating magnet, which in operating its saidower-bar ectuates said movable part which as previously been positionedfor such actuation. My said inventhe pending application in that itincludes a lockmg device which operates automatically to lock themovable part after being positioned until the power-bar has actuated it,which said locki device insures the proper positioning oft e movablepart unti the powerbar has effected its function.

Havin thus fully described my invention,
